according to the methodology below, i mixed chitosan solution with CaCl2 and NaHPO4 solution. How can I know that the calcium and phosphate ions are attached to chitosan chemically or physically? this solution was used in enamel remineralization and was prepared as follow:
Chitosan powder (0·25 g) was dissolved in acetic acid solution (1%,
25 ml), then stirred at 80°C for 2 h and finally left to cool to room
temperature. Following this, the solution was loaded with inorganic
ions by mixing chitosan solution (960 ml), sodium hydrogen
phosphate solution (15 ml, 0·1M) and calcium chloride solution
(25 ml, 0·1M).24 The pH of the mixed chitosan solution was adjusted
by adding sodium hydroxide solution (1 M) drop by drop until pH
6·5 was reached, at which point the chitosan hydrogel was formed.
To determine whether calcium and phosphate ions are chemically or physically attached to the chitosan in your hydrogel, you can explore a few analytical techniques:
Each method provides insights into either physical or chemical interactions, so using a combination of these techniques would give a clearer picture of the binding nature in your hydrogel.
Mahmoud Elshahawy, can i discuss with you the results of FTIR, XRD and EDX ?
Salma Ahmed Sure, I’d be happy to discuss the results of FTIR, XRD, and EDX with you. What specific details or questions do you have?
Mahmoud Elshahawy i want to send them in a message but i don't know how ?
Send your results via e-mail.
I have sent my e-mail in a private message.
Mahmoud Elshahawy i sent you the data since then ,, did you receive them ?
I received them and I sent you a pdf file containing my interpretation of the results on Monday 11 November. Please check your e-mail inbox.
